Caplet [by YuChung Hsiao]
A C++ open source capacitance extraction. Specialized instantiable basis
function templates move the computational bottleneck of this integral
equation solver from the non-embarrassingly parallelizable matrix solver
to the embarrassingly parallelizable matrix setup phase. 90% parallel
efficiencies have been demonstrated on tens of cores. “Real-time”
capacitance extraction performance (could be used to generate 3D field
solver accurate parasitic capacitance values while dragging and stretching
wires with the mouse). CAPLET can directly handle GDS2 layout files into
capacitance matrices in both GUI and command line interfaces. The internal
extraction algorithm is specialized for VLSI interconnect structures but
not exclusively, as long as the structure is of Manhattan geometry and embedded in
uniform dielectric.

Squid(stable
quasiconvex identification) [by Kin Cheong Sou] An
open-source matlab tool for the generation of reduced order linear system
models from available transfer function data points. The tool is based on
a quasi-convex relaxation of a system identification problem subject to
stability and passivity constraints.

M2VerilogA:
[by Zohaib Mahmood] A wrapper
class which takes in S-parameter or Z-parameter file in `.snp' touchstone
format or .mat file in matlab and generates a compact dynamical model. The
code incorporates binary search to find minimum system order for given
error bound. The final model is saved in a verilogA file which can be
easily interfaced with commercial simulators such as spectre.

open source MATLAB code for automated design of a decoupling matrix
connected between the power amplifiers and coupled RF arrays. This
decoupling matrix mixes the input signals and transforms the impedance to
ensure all forward power is delivered to the load
